16 GB DDR5 4800 SODIMM

This 16 GB DDR5 module runs at 4800 MT/s with CL40 latency and 1.1 V operation. It uses the standard 262-pin SO-DIMM form factor and is unbuffered non-ECC memory. The part is built to JEDEC and RoHS specifications for broad laptop, all-in-one and NAS compatibility.

Laptop and NAS upgrades only

The module suits owners of laptops, all-in-one PCs or NAS units that accept DDR5 SO-DIMM memory. Systems requiring registered or ECC memory cannot use this unbuffered non-ECC stick. Buyers needing capacities beyond 16 GB or a different voltage should look at other modules.

Speed decides fit

The single specification that determines compatibility is the 4800 MT/s DDR5 rating (PC5-38400). Your device must support DDR5 at this data rate with 1.1 V signalling and CL40 timing for the module to function correctly.

商品問答

Does my laptop need a 262-pin DDR5 SO-DIMM slot to use this 16GB module?

Yes — this module is a 262-pin DDR5 SODIMM that requires a DDR5-capable laptop, all-in-one or NAS slot.

Will this CL40 DDR5-4800 stick run at its rated speed if I keep an older DDR5-4800 module in the second slot?

Both modules share the DDR5 4800 PC5-38400 specification, so the system will operate them at the common 4800 MT/s rate with CL40 timing.

How can I verify the module is detected at 4800 MT/s with CL40 after installation?

Check the memory tab in CPU-Z or the firmware/BIOS main screen — it should report 4800 MT/s, PC5-38400 and CAS latency 40 for the installed 16GB module.
